In 2000, as a prelude to the release of the first harry Potter film, Harry Potter and the Stone of the Wise; Warner Bros., the film`s distributor, sent a series of letters to the owners of Harry Potter Fansites and requested that they hand over their domain names to protect their copyright.  The action led to negative publicity for the company when the 15-year-old webmaster of British fan site harrypotterguide.co.uk was moved to tears by what her father described as a tactic of unnecessary harassment. Finally, the company withdrew in the face of media opposition and stated that the site was not commercial and that it was not contrary to the brand.   The series caused further controversy in 2005, with the publication of the sixth book Harry Potter and the Half-Blood Prince, when a Real Canadian Superstore grocery store accidentally sold several copies before the approved release date. Canadian publisher Raincoast Books has obtained an injunction from the Supreme Court of British Columbia that prohibits buyers from reading the books in their possession. A comment by a media lawyer that "there is no human right to read" gave rise to a public debate on whether free access to information was a human right. Michael Geist, president of Internet research and e-commerce at the University of Ottawa, said: "Copyright was particularly enigmatic. While copyright can give copyright holders a basket with exclusive rights, the right to prohibit reading is not one of them. In fact, copyright doesn`t have much to say about what people can do with a book once they`ve bought it.   Independent activist Richard Stallman posted a statement on his blog calling for a boycott until the publisher issued an apology to the public.  Lawyers Fraser Milner and Casgrain, the Raincoasts, who made the legal argument in favour of the embargo, refuted this by stating that the Canadian Charter of Rights and Freedoms applied only to the government, not to private litigation, and did not offer the protection of the right to read, and innocent purchasers of the Harry Potter book would no longer have the right to read it when they were in possession of a secret.  Fidelius` charm functions as a contract between the magicians with a deal/promise to become someone`s secret keeper, as Dumbledore was for Grimmauld Place until his death, and Peter Pettigrew was for the Potters.
